Calving Ease Direct (CED) characterizes an animal’s genetic
potential for unassisted births in first-calf heifers, with a higher
value being more favorable to influence calving ease.
BirthWeight (BW) is an indicator of calf weight, with a lower
value characterizing lighter birth weight calves.
WeaningWeight (WW) is an expression of genetic potential
for calf weight at weaning, with a higher value indicating more
pounds of weaning growth.
Average Daily Gain (ADG) describes an animal’s genetic
potential for postweaning rate of gain. Directed toward the
feedlot period, a higher value indicates more average
daily gain.
YearlingWeight (YW) describes an animal’s potential for
postweaning gain measured near one year of age, with a
higher value reflecting more total pounds.
Residual Feed Intake (RFI) describes an animal’s feed intake
above or below its predicted need for maintenance and
growth. Lower scores indicate less intake.
Dry Matter Intake (DMI) is an expression of feed intake on
a dry matter basis. A higher value characterizes more feed
consumed by the animal, while a lower value indicates the
animal has potential to eat less feed.
Yearling Height (YH) characterizes an animal’s genetic
potential for height or frame, with a higher value indicating
more yearling size measured at the hip.
Scrotal (SC) characterizes an animal’s genetic potential for
scrotal circumference, with a higher value indicating more
yearling scrotal size.
Docility (DOC) is the animal’s genetic potential to be
extremely calm, or to have calm offspring. Higher values
indicate an improvement in cattle temperament.
Heifer Pregnancy (HP) is used as a tool to increase the chance
of a sire’s daughters becoming pregnant during a normal
breeding season. Higher scores are considered more favorable.
Maternal Calving Ease (CEM) characterizes an animal’s genetic
potential for unassisted births in first-calf daughters. A higher
value would indicate more favorable genetics for the ease with
which daughters calve as first-calf heifers.
Maternal Milk (MILK) is an indicator of milk and mothering
ability as expressed in daughters. A higher value characterizes
more milk expressed in pounds of weaning weight in a
daughter’s calves.
MatureWeight (MW) is an expression of genetic potential
for mature cow weight at six years of age, with a higher value
indicating larger cow size in pounds.
Mature Height (MH) characterizes the genetic potential for
mature cow height at six years of age, with a higher value
indicating larger cow size in frame or height at the hips.
Carcass Weight (CW) is a genetic predictor of hot carcass
weight as measured at harvest time. A higher value
characterizes more pounds expressed.
Marbling (MARB) is an expression of the potential to improve
the USDA marbling score, which is used to predict Quality
Grade in beef cattle. A higher value indicates a higher
marbling score.
Ribeye Area (RE) is a predictor of ribeye area in a carcass of a
sire’s progeny compared to progeny of other sires. A higher
value indicates a larger ribeye area.
Fat Thickness (FAT) is a predictor of the differences in external
fat thickness as measured between the 12th and 13th carcass
ribs. Lower scores indicate less external fat.
Tenderness (TEND) represents the genetic potential for
tenderness as measured by the Warner Bratzler shear force
test, with the higher profile scores being more tender than
lower scores.
American Angus Association®
Genomic-enhanced EPDs
FACT Sheet
Genomic-enhanced expected progeny differences (EPDs) for multiple carcass traits are calculated using the American Angus Association®
carcass and ultrasound data in combination with the IGENITY® profile for Angus. Together, the information provides a more thorough
characterization of economically relevant traits with improved accuracy on young animals. Additional traits are also evaluated, and producers
can access the Igenity profile scores on traits not currently expressed in EPDs.
